Migrating webservices from JAX-RPC to JAX-WS

I am migrating webservices from JAX-RPC to JAX-WS.webservices is deployed in WAS server and consuming in c#.In C# webservice service name is AuthnticationWebServiceService and wsdl name is AuthenticationWebService.wsdl in case of JAX-RPC.

JAX-WS service name is AuthenticationWebServiceService but in client place it is creating AuthenticationWebServiceService.wsdl.I don't want to change client code.

client place wsdl name is AuthenticationWebService.wsdl and service name is AuthenticationWebServiceService.
